statsmodels 摘要中的哪个值与图中的误差条大小相关？

Question

通过以下代码，我得到了一个图，我的数据是如何进行回归的。

图中还显示了垂直（错误？）条。

summary 中的哪个数字分别表示这些条的长度：如何从摘要（或从模型中检索到的任何数量）推导出条的大小？

代码：

import random
random.seed(42)
import statsmodels.api as smapi
from statsmodels.formula.api import ols
import statsmodels.graphics as smgraphics
# Make data #
x = list(range(30))
y = [y*(10+random.random())+200 for y in x]
# Add outlier #
x.insert(6,15)
y.insert(6,220)
x.insert(6,16)
y.insert(6,295)
# Make fit #
regression = ols("data ~ x", data=dict(data=y, x=x)).fit()
# Find outliers #
test = regression.outlier_test()

outliers = ((x[i],y[i]) for i,t in enumerate(test.iloc[:,2]) if t < 0.5)

print(regression.summary())

figure = smgraphics.regressionplots.plot_fit(regression, 1)
figure.show()

总结：

statsmodels 摘要中的哪个值与图中的误差条大小相关？

它们不是“误差线”。它们是预测区间，不能从摘要输出中计算出来。
